What else can I help you with?
What three ways would let you know that a reaction of a metal had taken place?
Observation of a change in the appearance of the metal, such as discoloration or formation of a patina. Production of bubbles or gas, indicating a chemical reaction is occurring. Increase in temperature or release of heat during the reaction.
What is an example of an chemical change a gas is produced may be seen as bubbles?
An example of a chemical change that produces gas and can be observed as bubbles is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid). When these two substances combine, they undergo a chemical reaction that produces carbon dioxide gas, which forms bubbles. This effervescence is a clear indication of the gas being released during the reaction.
What kinds of bubbles are there?
There are soap bubbles, carbon dioxide bubbles in carbonated drinks, air bubbles trapped in ice, and bubbles of gas released during fermentation processes like in beer or bread-making.
What is a heat reaction?
This the heat released during a chemical reaction.
What is gas evolved?
When a gas is released as a byproduct of a chemical reaction, it is referred to as gas evolved. This gas is usually observed as bubbles forming or a visible release of gas during the reaction. Examples include the evolution of oxygen in the electrolysis of water or the release of carbon dioxide in the reaction between baking soda and vinegar.

What is being produced when bubbles are present during a chemical reaction?
a gas

What is released during the light reaction?
Carbon dioxide is released during the light reaction.
What substance is released during the light reaction?
Carbon dioxide is released during the light reaction.
When energy is released during a reaction it is considered what type of reaction?
When energy is released during a reaction, it is considered an exothermic reaction. This means that the reaction is giving off heat to the surroundings.
What is the reaction when zinc reacts with sulphuric acid?
We can see bubbles of gas being released. The gas is a new substance, so this is evidence that a chemical reaction is taking place. the gas released during this reaction is hydrogen.
What kinds of bubbles are there?
There are soap bubbles, carbon dioxide bubbles in carbonated drinks, air bubbles trapped in ice, and bubbles of gas released during fermentation processes like in beer or bread-making.
What is a heat reaction?
This the heat released during a chemical reaction.
What is the effervescence test?
The formation of gas bubbles in a liquid during a reaction is called effervescence. It is the process of bubbling as gas escapes.

Examples include the evolution of oxygen in the electrolysis of water or the release of carbon dioxide in the reaction between baking soda and vinegar.
What type of Gas does the Reaction of Sodium Bicarbonate and Dilute Hydrochloric Acid produce?
When sodium bicarbonate reacts with dilute hydrochloric acid they produce carbon dioxide (CO2)
